HYDRooARBoN-LAMP.

SPEGIFIGA'ION forming part of Letters Patent No. 691,068, dated January14, 1902.

Application filed April 20. 1899. Serial No. 713,723. (No model.)

T l/ZZ when?, it may col/warn.

Be it known that I, STEPHEN B. MORSS, a citizen of the United States,residing in Rahway, Union county, New Jersey, have invented certain newand useful Improvements in Hydrocarbon-Burning Lamps or Heaters, ofwhich the following is a specification.

My invention relates to improvements in the class of lamps or heaters inwhich vapor or gas is evolved from hydrocarbon oil and commingled withair, the mixture to be burned in the form of a sootless or blue flame;and the object of my invention is to provide improvements in the devicesthat generate the vapor or gas.

In carrying out my invention I provide a primary combustion-chamber inwhich is located an oil-burner of anysuitable type adapted to producewhat is known as a white flame, and in. conjunction therewith I use awick that leads to'an oil-font, which wick is in proximity to oroverlies said burner, so that the heat from the flame will cause vaporor gas to be evolved froml the oil carried up by the wick. Said Wick isprotected from the flame, and by preference the Wick is guided by ametallic duct or tube which is provided with one or more perforations oropenings for the escape of vapor orgas, whereby the heated metal of theduct assistsin evolving the vapor or gas from the oil. I also preferablysurround ihe `perforations or openings of the duct with a band of, metalto prevent the llame from` reaching the gases or wick. Thecombustion-chambeis connected with a suitable air and vapor or gasmixing chamber, to Which a secondary'or supplemental burner is connectedin any suitable or Well-known manner.

The invention also consists in the novel details of improvement and thecombinations of 'parts that will be more fully hereinafter set forth andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming parthereof, wherein- Figure 1 is a vertical section of a lamp embodyingmyimprovements. Fig. 2 is a cross.- scction on the line 2 2 in Fig. l;and Fig. 3 is a section substantially on the line 3 3 in Fig. 1, theshield for the burner being removed. i

In the accompanying drawings, inwhicb `similar numerals of referenceindicate correspending parts in the several views, 1 indicates asuitable oil-font, and 2 is a burner of suitableconstruction adapted tobe connected therewith, being shown` provided with a perforated top 3,air-inlets et, and a wick-tube 5, adapted to receive a wick 6, thatpasses in to font 1, 7 being an ordinary toothed wheel for controllingthe wick.

S is a shield or air-guide surrounding the upper portion of tube 5 tocause the proper burning of a dame at the end of wick 6 in well-knownmanner.

The above-described parts may generally he in any well-known or suitableconstruction adapted for producinga white Haine from hydrocarbon oil.Above the perforated top 3 I provide a combustion-chamber composed of ashell 9, that is shown resting upon the top 3, the latter having aflange or shoulder 3n to hold the shell 9 in position, whereby the shell9 is removable; but these parts may be otherwise arranged and connected,if desired. The shell 9 is provided with an opening 9, adapted to beclosed by a shutter or the like l0, suitably arranged thereon to permitaccess to the interior of the shell, as for lighting the wick 6.

The oil from which vapor or gas is to be produced is conducted from thefont by means of a feeding-Wick located in proximity to, but preferablyacross the top of the iame from, wick 6, and the feeding-Wick isprotected from the flame by a partition. For these purposes I have showna duct or tube ll, illustrated as curved atits central portion andprovided with two depending leg portions that pass through the parts 2and 3 and open into the font l, whereby a wick can be located in saidtube and depend at both ends into the font. The upper surface of thetube or duct ll at the part 11L that crosses the top of tube 5 isprovided With one or more openings or apertures llb (see Fig. 2) for theescape of vapor or gas that is generated by the oil carried into theduct by the wick. I have shown the wick Gas depending from tube 5 andpassing over a pin or guide l2 in font l, thence up through d uct 1l,across over tube 5, and down through said duct and depending into thefont 1. By this means as the wick is consumed at the burner-tip and isfed IOO Y sented over the llame.

forwardly new parts of the wick will be pre- It is evident, however,that separate wicks can be used-that is to say, one wick can depend fromthe tube and the other wick can pass through the duct 1l and depend fromboth ends thereof,

vextends upwardly and conducts the vapor g away from the zone'of `thedame.

The combustion-chamber 1n which the va- Y por or gas is generated is tobe connected with Iable or well-known manner.

a'gvapor or 'gas and air mixing chamber, the latter' beingfconnectedwith ay supplemental burner, all of which' may be made in any suit- Ihave shown the shell 9 as connected by'tubes 91 with a 1niXing-chamber13, shown provided with air? inlets 13, a burner 14 beingconnected withthe latter.y

From the foregoing it will be understood Y that when'it is desired toproduce vapor or ber.

rgas from hydrocarbon oil the wickis lighted at the burner-tube 5 andthe sizeof the flame cau be regulated in well-known manner. The heatfrom the llame will act upon the oil conducted by the wick within theheating zone of the fiame in such manner as to cause vapor or gas to beevolved therefrom, and the proportion of such vapor or gas which isevolved willbe determined, more or less, by the size of the Haine usedin the combustion-cham- The vapor or gas 4Vthus'evolved passes from theduct or tube l1 through its openings 1lb up-into the mixing-chamber, andit is then burned at a suitableburner in the y yform of'a sootless orblue flame either for heating purposes or for producing alight, as

'from a refractory mantle l5 in well-known lnanner.

The advantages of my improvements are 'A that there is no necessity ofsmothering the' y:flame that produces thel heat for evolving the vaporor gas, and as the vapor-producing. flame is'not smothered the same willbestrong and will therefore not be liable to fluctuations due to changesin air-circulation around the lamp, and, furthermore, the heated metalof the partition, duct, or tube ll in contact with the oil-feeding wickwill have an effect more fully to evolve the gases from the oil. I thusdispense with valves and adjustable devices for feeding the oil, theauxiliary or feeding wick being automatic in its action as to the supplyof oil, the height of the heating-flame regulating the quantity of vaporo gas evolved.

In my improvements there is very little unconsumed products ofcombustion passing away from the generating or heating flame, and thechamber within band 11C, in which the'vapor or gas is evolved from thefeeding or auxiliary wick and allowed to escape, is almost entirelyseparate from the combustionchamber. y

I do not limit my invention to the precise details of construction shownand described,

as they may be varied, as necessity or prac-- tice may suggest, withoutdeparting from the spiritof my invention.

Having now described my invention, what I claim is-- y l. In a lamp orheater of the character described, the combination of a burner havinga'l'wick-tube, and a tube or duct having a portion overlyingthewick-tube 5 and two depending portions lying on opposite sides ofwick-tube 5 and opening downwardly, and a wick extending continuouslyfrom Wick-tube 5 to an oilfont,thence upinto and through the ductandfdepending therefromI into the oil, the overlying portion of the ducthaving means to permit the escape of vapor, substan-v tiallyas'described. l
